CHARLES IB. DALZELL, OF LITTLE FALLS, NEW YORK, ASSIG'NGB TO D. H. BUBRELL COMPANY, OF LITTLE FALLS, NEW YORK.

MILKIIING-MACHINE.

Application med March 24, 1917. serial No. 157,087.

To all whom t may concern:

Be it known that I, CHARLES B. DALZELL, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Milking-Machines, of which the .followingis a specification.

This invention relates to improvements in milking machines and more particularly in milking machines of that sort adapted to simultaneously milk two cows, in which the receiving pail is divided by a partition into two compartments so as to keep the milk from the cows separate. Heretofore, -it has been usual to provide these compartment pails with ouring spouts arranged at one side thereoi) at opposite sides of the partition to enable the milk to be' poured simultaneously from both compartments of the pail into two buckets or receptacles standing side by side, and the milker pail has been made of upwardly tapering form or with a top portion of smaller diameter than the bot tom of the pail. This was to make the pail stable and give it a fair capacity and at the same time reduce the size of the pulsator or milking mechanism on top of the pail to what wasconsidered a good practical size. The large bottom of the pail also served. to protect the projecting pouring spouts from injury by contact wlth an object.

Milking machine pails of this construction, however, have serious disadvantages. It is diiiicult to properly clean and wipe out the pails on account of the small size of the upper ends of the compartments and air does not circulate in the pail so as to thoroughl dry it `when the pail is inverted after waslling. This type of partitioned pail is also much more expensive and diicult to manufacture and requires more stock for a pail of the same capacity than a straight sided or cylindrical pail in which the partition is of like width from end t0 end. Onthe other hand projecting, pouring spouts would be objectionable on a straig' t sided or cylin r1cal pail because they'would not be protected and would be apt tobe struck and injured.

t The objects of this invention are to produce a practical and desirable compartment milking machine pail, preferably of straight sided or cylindrical form, havin a Eourm deiectdr' so arranged as to enab t e mi Specication of Letters Patent.

to be readily poiired simultaneously from the two compartments of the pail and both compartments to be also to provide the which projects above the rim of the pail so completely drained.;- pail with a partition that the pail'can be placed upside down and be held by the partition in a tilted position, which enables free circulation o air in the compartments of the pail and insures thorough drying of the same after the pail has been washed; also 4to improve milking machines in the other respects', hereinafter described and set forth in the claims.

In the accompanying drawings Figure -1 of a milking machine embodying the invention.

Fig. 2 is an elevation, on'a reduced scale of the milkerv pail inverted for draining'and drying it. l

Fig. 3 is a plan view, reduced, of the pail with the cover and pulsator removed.

Fig. 4 is a sectional elevation of the pail in line 4 4, Fig. 3.

,Fig 5 is a sectional elevation of the pail on line 5--5, Fig. 3 on an enlarged scale.

A represents the ail or milk receptacle of the milking machlne, B the cover or top for 4the pail and C the pulsator mounted on the cover B, which thus constitutes the supporting base for the pulsator or milking mechanism. The pulsator or milking mechanism, andthe stop cocks or, valves d for the nipples or connections D D' to which the milk tubes are` connected, maybe of 4any usual or suitable construction. E is the usual pulsator piston which reciprocates in an open bottomed cylinder e for causing pulsations in the teat cups. The milk pail, asusual,'is `divided by a partition F into two compartments f f for separatin the milk from the two cows,- and the piston is located above this partitlon and is constructed partments of the' is preferably of substanis an elevatlon, partly in section,.

to deliver the milk'rom the two milk connections D D into the two comrical shape -or of substantially t0 -be made large enough to afford ready access to the compartments for vwashing `and wiping them. The partition F preferably has a curved or arched upper edge which projects upwardly above the rim or upper.

end of-thepail' and slopes downwar ly fromits middle portion, joiping the wall of the .pail substantially flush with itsrim or upper H represents a pouring vdelector which is located inthe upper end of the compartlment f of the pail for the purpose ofdirecting the stream of milk from this compartment when lemptying the pail. This deflector extends inwardly from the cylindricalwall of the pail at one side only of the partition, there being nov delector for the compartment 7" at the opposite s ide of the iartiector tion. Preferably that edge L of the d which joins and is soldered or otherwise suit- -ably secured to the partition, inclinesy upwardly and inwardly from its outer end which is below the rim of the cylindrical wall of the pail to its inner end which is above the rim ofthe pail,"as clearly shown in Fig. 4. The outer edge h of the deliector which joins and is soldered or otherwise suitably se cured to the cylindrical wall of the .pail

' preferably slopes upwardly from the partition F 'to a pointsubstantially flush with 4 the upper edge of the rim of the pail,'as shown in Figs. l and 5. The deflector is also preferably provided along itsremaining edge, .which extends at an angle from the partition to the wall of the ail, with an upt'urned lip or iiange h2. en the milk is being poured from 1the pail the deflector H deiects the milk from the compartmentV f in which itfi-s located away from the partition F, thusfkeeping the streams of milk Vdischarging from the two compartments '-separate, and enabling the milk to be simultaneously poured from the two com artf 'ments into two receptacles standing si e by side. 'As the -deflector is located at one side only of the partition it is very easy to completely7 pty-or drain both compartments of the. pai, because the milk will 'readily drain from the compartment f in which there 1s no delector and "tl'iie..-pail can then be tilted `slightlylfto one'side to comllletly` ef.

-I is preferably pivoted to the pail in a plane .perpendicular to a line w-w, Fig. 3, extending through the through the middle of the outer edge h center ofthe partition and l of the deiector H, and the pai-l is provided with a pouring handle K which is located t the opposite side of the pail from the deector.

-Since the partition F projects above the upper end or rim of thepail, the pail can l' be stood upside down ina tilted position, as indicated 1n partition and one side of the rim of the pail. In this position, the pail Will drain -and Aair cani freely enter and circulate inl both compartments of the pail, thus insuring" theproper drying of the pail after Awashing it. The projecting -partition also assists in preventing injury to the rim'of Fig-2, in which it rests on the'- the pail, which should be kept 'intact to insure a tight joint with. the .'cover.

vThe pail cover or pulsator base B is preferably of dome shape or of arched form in' cross section with its middle portion highest so that the pulsator which is carried by the coveris supported well above the rim of the pail A and ample air space is left in the cover above the rim of the pail to prevent the 4foam or milk from bein drawn up into the vacuum connections w en the pail is full. The rim of the cover can be construct;-I ed in any suitable way to t the pail and in sure an airtight joint between the cover and the pail. As shown,'the cover is rovided with a vertical rim flange Z W ich extends down inside of the` rim of the pail and with a flange .Zv which projects outwardly and downwardly over the rim ofthe pail. Z2 is a pack-ing gasket coniined in the groove formed |between the ianges l and l and adaptedto bear on the rim of the pail to Vform an air ti' ht 'joint between the cover and rthe pail.- he depending ian` Z o the cover shownis notchedl at l l* to't over the' edges ofthe partition Hector. As- 'the cover is dome-sha ed or arched it can be inadeof much lig ter 'or thinner material than a4 flat cover of equal diameter and nevertheless have .adequate strength te withstand the atmospheric pressure on theV same, which is very (greatwhen stati vacuum is maintained in the pail.
